#### Geeks: We've Got Your Number

Regular numbers? Those are for amateurs. Bring your inner genius out for all to envy with a smart and stylish watch that features the equivalent notation of each number.

For nascent mathematicians and victims of the occasional memory lapse, a cheat sheet is included with each watch.:
1: i is equal to the square root of -1, so i^2= -1. The absolute value of -1 is 1.
2: This represents 2 in binary code.
3: The cube root of 27
4: 11 base 3, which represents 4 in the ternary system
5: Log(20x)=2 is equivalent to 20x=10^2 or 20x=100, where x=5.
6: Euler's product formula: phi(p^k)=(p^k)(1-(1/p)), where (p^k)=9
7: This is a binomial coefficient, so with the formula n/k = (n!)/((k!)(n-k)!), n/k=7.
8: This is a natural logarithm where ln(e^x)=x, so ln(e^8)=8.
9: This summation is equal to 3(1)+3(2)=3+6=9.
10: Since clocks "wrap around" every 12 hours, the hour number starts over after it reaches 12. This is arithmetic modulo 12. 10mod12 is 10:00, and 16mod12 would be 4:00, for example.
11: B'L is Legendre's constant, which is equal to 1, so this equation becomes the square root of 121, which is 11.

Made in China. Japanese movement. 3 ATM water and splash resistant.

Great product. He really loved that the equations were accurate (bought a similar wall clock and the numbers needed to be rounded, which drove him nuts). Got it in black, so it was very easy to read. The packaging was great! Unfortunately, the wrist band kept snagging his arm hair, so he had to replace it. Also he forgot to take it off when working on a vehicle and scratched the face, so that'll have to be replaced, too. Probably not for everyday where if you tend to get your hands dirty, but otherwise we are both really happy with it.

Some guys are just hard to buy for and this is perfect for my brother - a computer center manager at one of the geekiest universities in the world. The watch say UberGeek and makes a real statement. And it was priced reasonably. Packaging (which was also nice) was damaged in shipment - square box would have traveled better than cylindrical.

My husband loved the watch a lot. This is the first that I've seen such a watch; unusual, classy, great wrist attention! BUT, my husband was only able to wear it a few times before the clasp that held the band together started to loosen. I requested a replacement, which the company honored. Still waiting for the return label via email.

For A College Math Professor, it's perfect.
I would have made the equations bolder and the face material less bland. But, it works.
